Environmental Compliance
Waste Electrical and Electronic Equipment (WEEE) Directive
Panametrics Solutions is an active participant in Europe’s
Waste Electrical and Electronic Equipment
(WEEE)
take-back initiative, directive 2002/96/EC.
The equipment that you bought has required the extraction and use of natural resources for its production. It may
contain hazardous substances that could impact health and the environment.
In order to avoid the dissemination of those substances in our environment and to diminish the pressure on the
natural resources, we encourage you to use the appropriate take-back systems. Those systems will reuse or recycle
most of the materials of your end life equipment in a sound way.
The crossed-out wheeled bin symbol invites you to use those systems.
If you need more information on the collection, reuse and recycling systems, please contact your local or regional
waste administration.
Visit www.bakerhughesds.com/health-safetyand-environment-hse for take-back instructions and more information
about this initiative.

Chapter 1. Features and Capabilities
1.1 Overview
This chapter presents the features and capabilities of the TMO2D Digital Display. It also includes a brief list of
Panametrics transmitters that can be used with the TMO2D Digital Display.
1.2 Introduction
The TMO2D Digital Display offers a number of important features:
• 24 VDC 1A maximum power supply for the transmitter.
• A single isolated 0/4–20 mA output, with the option to add a second 0/4–20 mA output.
• Up to four field-programmable alarm contacts with the option of being hermetically sealed for Division 2
applications. Each alarm can be programmed for both a high and a low setpoint, and also for either failsafe or
non-failsafe operation.
• Optional automatic calibration of Panametrics transmitters.
• A fault alarm in the event of either a transmitter problem or a calibration error. The fault alarm can be
programmed for either failsafe or non-failsafe operation.
• A 2-line x 24-character backlit LCD display.
The TMO2D Digital Display supports any of the following Panametrics transmitters:
• XMO2 or TMO2 thermoparamagnetic oxygen transmitters
• XMTC or TMO2-TC thermal conductivity transmitters
• O2X1 oxygen transmitter
Note:
For information on specific transmitters, please consult their respective manuals.

Chapter 2. Installation
Chapter 2. Installation
2.1 Overview
This chapter describes how to mount and wire the TMO2D Digital Display. It also contains information on connecting
the TMO2D to optional system components. The following topics are discussed:
• Mounting the TMO2D digital display.
• Wiring various Panametrics transmitters to the TMO2D display.
• Connecting to other components.
WARNING! To ensure the safe operation of the TMO2D, it must be installed and operated as described in this
manual. In addition, be sure to follow all applicable safety codes and regulations for installing
electrical equipment in your area. All installation procedures should be performed by trained service
personnel.
2.2 Mounting the Electronic Display
The electronic display comes in six mounting configurations: bench, rack, panel, fiberglass NEMA 4X, 304 stainless
steel NEMA 4X and explosion-proof. (See Appendix A for mounting dimensions).
No special mounting requirements are needed for the display. If you have a bench mount, simply put the display in a
convenient location, connect the wires from the transmitter, and connect the power. If you have a rack or panel
mount, insert the display into the rack or panel, connect the wires from the transmitter, and connect the power. The
weatherproof and explosion-proof models are wall mounted.
IMPORTANT: For compliance with the EU’s Low Voltage Directive (2006/95/EC), this unit requires an external power
disconnect device such as a switch or circuit breaker. The disconnect device must be marked as such,
clearly visible, directly accessible, and located within 1.8 m (6 ft) of the unit. The power cord is the main
disconnect device.
2.3 Wiring Transmitters to the TMO2D Display
This section explains how to interconnect the TMO2D display with four different Panametrics transmitters: TMO2,
XMO2, TMO2-TC and XMTC.
2.3.1 TMO2 Transmitter
This section describes how to interconnect the TMO2 and TMO2D. The TMO2 can be wired for internal or external
compensation. Each type of compensation requires a different cable. Before you make any connections, make sure
you have the appropriate cable. Please check the TMO2 calibration sheet to determine if your TMO2 has internal or
external compensation.
• Internal compensation offers a single 4–20mA output for O2 concentration that is compensated for either
background gas or atmospheric pressure variations.
• External compensation offers dual 4–20mA outputs, one for uncompensated O2 concentration and the other for
either background gas or pressure compensated O2 concentration. This type of compensation is normally used
with the TMO2D Display, which can be programmed to provide microprocessor-based background gas or
pressure compensation of the O2 signal.
2.3.1.1 Cable Requirements:
• Internal compensation: X3(*) or Y3(*) 3-wire 22-AWG cable.
• External compensation: X4(*) 4-wire 22-AWG cable.
Chapter 2. Installation
4 TMO2D User’s Manual
The X3(*) and X4(*) cables can be used for distances up to 450 ft (130 m). For longer distances, each cable can be
supplied as 18-AWG that can be located up to 1,050 ft (320 m). If you are using your own cable, refer to Table 1 below
for cable requirements.
For longer cable lengths, consult the factory.
2.3.1.2 Wiring:
Use the following steps to interconnect the TMO2 to the TMO2D.
1. Route the cable into the TMO2 transmitter through one of the 3/4" conduit holes on the side of the transmitter.
WARNING! Be sure to plug the unused conduit/cable entry hole on the transmitter, in order to meet
specifications and to maintain the appropriate weatherproof or explosion-proof rating.
2. Unplug TB1 on the TMO2 transmitter PC board (PCB) by carefully pulling it directly up without bending the pins
attached to the PCB.
3. Loosen the TB1 side screws and insert the colored wires into the corresponding openings on top of TB1. See Table 2
below for color-coded pin designations, and Figure 1 on page 5 for the TB1 location.
WARNING! Make sure that the +24 VDC wire (red) is connected to terminal TB1-1. Connecting +24 VDC to any
other other terminal could cause bodily harm. It could also cause damage to the TMO2 PCB, requiring
factory repair.
4. Tighten the side screws, and carefully plug TB1 back onto the TMO2 PCB.
5. Connect the other end of the cable in a similar manner to the TMO2D. Refer to Figure on page 17 for TB1 location.

2.3.1.3 CE Mark Compliance
IMPORTANT: CE Mark compliance is required only for units used in EU countries.
For CE Mark compliance, you must use shielded cable and connect the shield to the stand off as shown in Figure 2
below. After you make all the necessary electrical connections, seal the unused cable entry holes with standard
conduit plugs or their equivalent.
Note:
If you make the modifications as discussed here, your unit will comply with the EMC Directive 2004/108/EC.
Note:
For CE compliance, the I/O cables must be shielded. The shields are to be grounded within the TMO2D to the
closest location.Shielded cable is not required when installations include metal conduit.

2.3.2 XMO2 Transmitter
Wiring the XMO2 oxygen transmitter to the TMO2D display requires use of the X4(*) cable, which can support
distances up to 450 ft (130 m). For longer distances, each cable can be supplied as 18-AWG that can be located up to
1,050 ft. (320 m). If you are using your own cable, refer to Table 3 below for cable requirements.
For longer cable lengths, consult the factory.
2.3.2.1 Wiring:
Use the following steps to interconnect the XMO2 to the TMO2D.
1. Route the 4-wire power/analog output cable through a cable gland as shown in Figure 3 below.
2. After terminating the shield as shown, assemble the three gland pieces together and tighten the gland to secure
the cable and the shield.
IMPORTANT: The cable shield must be terminated in the cable gland as shown in Figure 3 below.
Figure 3: Proper Cable Gland Assembly
3. Route the cable into the XMO2 transmitter through one of the 3/4" conduit holes on the side of the transmitter.
